Hypericum plant named ‘Verivocla’

ABSTRACT

A new and distinct cultivar of  Hypericum  plant named ‘Verivocla’, characterized by its upright and outwardly spreading plant habit; dark green leaves; cream-colored fruits; and good postproduction longevity.

Botanical designation: Hypericum androsaemum.

Cultivar denomination: ‘Verivocla’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androsaemum, commercially used as cut stems with fruits, and hereinafter referred to by the name ‘Verivocla’.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in Wieringerwerf, The Netherlands. The objective of the breeding program was to develop cut Hypericum varieties with attractive fruit coloration.

The new cultivar originated from a cross-pollination made by the Inventor in January, 2000 of a proprietary selection of Hypericum identified as code number 121051, not patented, as the female, or seed, parent with a proprietary selection of Hypericum identified as code number 121062, not patented, as the male, or pollen, parent. The cultivar Verivocla was discovered and selected by the Inventor during the summer of 2001 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Wieringerwerf, The Netherlands.

Asexual reproduction of the new Hypericum by terminal cuttings at Wieringerwerf, The Netherlands since August, 2001, has shown that the unique features of this new Hypericum are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Verivocla’. These characteristics in combination distinguish ‘Verivocla’ as a new and distinct cultivar:

-   -   1. Upright and outwardly spreading plant habit.     -   2. Dark green-colored leaves.     -   3. Cream-colored fruits.     -   4. Good postproduction longevity.

Plants of the new Hypericum differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Hypericum have more compact flower umbels         than plants of the female parent selection.     -   2. Plants of the new Hypericum have smaller fruits than plants         of the female parent selection.     -   3. Plants of the new Hypericum and the female parent selection         differ in fruit coloration as plants of the female parent         selection have darker cream-colored fruits.

Plants of the new Hypericum differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Hypericum have longer stems than plants of         the male parent selection.     -   2. Plants of the new Hypericum have more rounded fruits than         plants of the male parent selection.     -   3. Plants of the new Hypericum and the male parent selection         differ in fruit coloration as plants of the male parent         selection have brownish white-colored fruits.

Plants of the new Hypericum can be compared to plants of the Hypericum cultivar Excellent Flair, not patented. In side-by-side comparisons conducted in Wieringerwerf, The Netherlands, plants of the new Hypericum differed from plants of the cultivar Excellent Flair in the following characteristics:

-   -   1. Plants of the new Hypericum had shorter and darker         green-colored leaves than plants of the cultivar Excellent         Flair.     -   2. Leaves of plants of the new Hypericum did not scorch as a         symptom of low leaf magnesium whereas leaves of plants of the         cultivar Excellent Flair scorched.     -   3. Plants of the new Hypericum had smaller inflorescences with         fewer flowers per inflorescence than plants of the cultivar         Excellent Flair.     -   4. Plants of the new Hypericum produced slightly smaller fruits         than plants of the cultivar Excellent Flair.     -   5. Fruits of plants of the new Hypericum were cream in color         whereas fruits of plants of the cultivar Excellent Flair were         brownish red in color.

DETAILED BOTANICAL DESCRIPTION

The new Hypericum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Wieringerwerf, The Netherlands, in an outdoor nursey and under commercial production practices. Plants used for the photographs and the description were about two years old. The photographs and description were taken during the summer with day temperatures ranging from 14 to 30° C. and night temperatures ranging from 7 to 14° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary siginficance are used.
